First-responder experience with MCS system1.- How easy is the MCS client to use? 4(considering 1: Very hard, 2: Hard, 3: Neutral, 4: Easy and 5: Very easy)

Could you elaborate? After minimal training we found all users were able to operate the MCS client with relative ease.

2.- In your previous experience with public safety communications, what do you miss most? Is the interoperability with other agencies a desirable feature?

Compared to a standard radio I miss the knobs on the top of the radio making turning the device on/off, volume control and switching channels easy and effortless. The speaker mic was not useful on the MCS as you did not know who you were calling/answering without looking at the display.Interoperability with other agencies is an extremely desirable feature.

3.- Which feature of the MCS client is the most important in your daily life? Why?

Coverage area is extremely important. Need the MCS to work when needed inside of buildings and throughout the city. This is important for officer safety. The MCS did not function when the bandwidth was congested during the Beach Concerts; whereas the phone and text messaging worked without issue on the FirstNet system.

4.- Which feature of the MCS client is the least important in your daily life? Why?

1)The MCS did not allow attachments (photo) and you had to leave the application to share a photo (although the video worked well).2) The main problem with the MCS client was the creation of an ‘Open Mic’. A sincle touch of the user to be called created an open mic (transmitting without keying the PTT) and the user could be unaware. This was very problematic and should be ELIMINATED.

5.- Is there any feature that you would strongly recommend us to add? Why?

1) Addition of an ALERT feature to signal the recipient of the call. Very useful in a high noise environment and to show an attempted call was missed.

2) Ability to share attachment in the application (photo) without exiting.3) Ability to use the application with others not on a Sonim platform (restricts available users).4) Administration portal to clone or set up all users remotely, and not have to program each device individually. Items like changing alias names, talk groups, settings etc.Attachment to the phone with knobs similar to a traditional radio.

6.- In the experience with the MCS client, please, describe a situation where the product was useful.

The product was useful during the beach concerts in Atlantic City. Our SWAT team utilized the sonim phones with MCS client to communicate amongst each other. The Firstnet netwok worked flawlessly while the traditional cellular networks were experiencing congestion issues making phone calls difficult. We had no issues on the FirstNet network.

7.- Do you foresee the future utilization of the MCS client? Do you want to be involved in the evolution of the MCS client?

Yes, if it is improved. and Yes.

8.- Could you describe a real issue in the field that could be solved with enhanced communications but yet, you have not found the appropriate product/solution?

With our current traditional radio network we are unable to communicate with other agencies if their radio channels were no preprogramed into our radio or a patch is not initiated. Need a more robust with the ability to add in users without any advanced notice.

9.- Would you recommend the MCS client to other first-responders?Yes, if improved.10.- Rate the overall experience. (considering 1: Very bad, 2: Bad, 3: Neutral, 4: Good and 5: Very good) 4

Could you elaborate?

Was a good experience, with further enhancements this product could be very useful to law enforcement. Some features of the ATT Client application should be examined.
